Absolutely. It crashes with straight ADO.NET. However, my actual query is a little more complicated and takes 5 parameters. The first 4 are Int64 but the last one is a string. I discovered that when I set the
size of the string it worked perfectly. How can I set the size of the parameter in the DAAB?

I also managed to get some other queries working by using only "?" as parameters (the working ADO uses "@name.")
